Severe facial asymmetry in adults with hemifacial microsomia or other types of mandibular hypoplasia is challenging to treat with simultaneous maxillomandibular distraction osteogenesis using an external distractor combined with intermaxillary fixation (IMF). Using an external distractor also produces significant distress for patients for at least 8 weeks. Furthermore, mandibular-driven distraction tends to elongate the midface, with difficulty positioning of the center of the maxilla in the center of the face and horizontalization of the occlusal plane...

Clinical evidence has suggested that surgical corticotomy of the alveolar bone can accelerate local orthodontic tooth movement (OTM), but the underlying cell and molecular mechanisms remain largely unclear. The present study examined the role of macrophages played in corticotomy-assisted OTM. Orthodontic nickel-titanium springs were applied to the left maxillary first molars of rats or mice to induce OTM with or without corticotomy. Corticotomy enhanced OTM distance by accelerating movement through induction of local osteoclastogenesis and macrophage infiltration during OTM...

Periodontally accelerated osteogenic orthodontics (PAOO) is a clinical procedure that incorporates selective corticotomy, particulate grafting, and application of optimal orthodontic forces. It reduces treatment time, increases stability of teeth, and prevents relapse of orthodontic tooth movement (OTM). The present case report highlights the technique and principles of PAOO for rapid OTM.

Limb lengthening by Ilizarov lengthens not just the long bone, but also the soft tissues too. Damage of the muscles during corticotomy and their stretching during distraction play a crucial role in occurrence of complications and final limb function. We present here a systematic codified nomenclature system of each muscle summarising all the influence that corticotomy and distraction have the particular muscle and demonstrate the same in the setting of tibial lengthening. This scheme helps the surgeon easily recollect what all muscles are involved in what all ways in each level of corticotomy thus enabling him to watch out for complications thereof and monitor and accordingly modify the limb lengthening process...

True intrusion is one of the difficult and complex goals to achieve which requires clinical judgment, skills, and experience. Intrusion requires less force level than other tooth movement, but it requires delicacy since the entire stress is concentrated in the apex of the root. Although true intrusion alone is not challenging, eliminating the adverse effect while intruding requires tedious skills of the clinician. A 17-year-old male patient with Class I malocclusion with open bite has a prominent maxillary cortical bone...
